Professionals are at their best regardless

The fact is, as a professional headshot photographer, your client hired you to make the best headshots / portraits that s/he has ever had, so there's no room for you to have a bad day - you need to be at your best every day and at every shoot

Regardless

As a client, you're allowed to have a bad day but when you show up for the shoot, it is MY responsibility as the professional to get the shot of you anyway - you're not responsible for your look or expression on that day - I am

You lay your professional brand and image in my hands and it's my job to make you look the best for your portrait, portfolio, LinkedIn profile or whatever you'll be using your professional headshot for

Along the same lines, when you deal with a professional, you have the right to expect consistency in the final headshots that are delivered to you; colors, sizes, retouching, etc. etc. all have to match so that you can appear professional and consistent across the various channels where your images will be used (LinkedIn, resumes, Facebook, etc.)
